UNITED STATES ADJUSTABLE BOX PLATE James M. Tuten, Hopedale, Mass., assignor to* Draper Corporation, poration of Maine Application September Claims.

The present invention pertains to fly shuttle looms and more particularly to shuttle boxes for such looms.

Looms of the type towhich my invention ap- 5 plies commonly include a lay sword, a lay beam fixed to the frontl face of the sword,la shuttle box including a back plate having a shuttle guiding surface, and means for securing such plate to the lay sword and lay beam. Theshuttle guiding plate must be accurately positioned relative to the lay beam, and relative to the reed, in order that the shuttle may be properly picked into and out of the shuttle box.

I propose to provide a loom having a lay sword, lay beam and shuttle box including a back shuttle guiding plate as aforesaid, and adjustable supporting means located at the back of the lay sword for supporting the shuttle( guiding plate, whereby the supporting means shall be conveniently accessible for adjustment purposes.

The foregoingand other objects of the invention are accomplished in the construction illustrated on the accompanying drawing, of which:

Fig. 1 is a view in rear elevation of part of a lay assembly having the preferred embodiment of my invention applied thereto;

Fig. 2 is a View in cross-section taken approximately on line 2-2 of Fig. 1; and

Fig. 3 is a plan View of the construction shown on Fig. 1.

The drawing shows but part of a loom having my invention applied thereto, the parts and mechanisms not shown being of any suitable usual construction and forming no part of the present invention. The drawing shows a section of the usual lay beam I which is fixed to the front face of a sword 2 below the top thereof in the usual manner. The sword 2 is at the left hand side of the loom and another sword, not shown, supports the other end of the lay beam. The lay beam and lay swords reciprocate toward and from the front of the loom, which is toward the right on Fig. 2. A suitable reed 3 is carried by the lay, and at least one shuttle box is provided at each side of the loom.

The shuttle box shown on the drawing is the left hand box and consists of a floor 4, a front box plate 5 and a back box plate 6. The floor 4 is formed by the upper surface of the usual metal lay end, so-called, which is fixed on the lay beam I. The front box plate 5 is fixed to the lay beam and the inner or right hand end of the back box plate is adjustably supported by the lay sword 2 in a manner to be described. I.

The back box plate 6 includes a plate 1 which Hopcdale, Mass., a cor- 2, 1937, serial No. 162,093

has a vertical front surface 8 for guiding the shuttle (not shown). The back box platev mayr also include a top shelf 9. A lug I0 on the plate 1 ,is preferably formed; integrally with; the plate and j extendsv rearwardly, substantially horizon-A tally, from the back of the plate. The lug IU extends through anlopening II in the sword 2 and is fixed to supporting means at the back of the sword. The opening II is appreciably larger than the lug I0, to permit adjustment ofthe lug and box plate. The Asole supportingmeans for theplate 1 maybe that shown at the back of the sword. n. Y ,Y n A The embodiment-of supporting means shown includes a member I2. which is located ladjacent the opening II and which has angularly related legs I3 andwI4. The .leg I3 is Vertical whilev the leg 4I4 is horizontal-and has an upper horizontal surface on which the rearward end of the luglll rests. The. vertical leg, I3` engages theinside. of a Y.vertical flange LI5on' the lay sword and is clamped t'o such flange by a bolt I6.` The bolt I6 passes through the leg I3 and through a Vertical slot I1 in the flange I5. This bolt and slot connection permits the member I2 to be adjusted vertically. by sliding the bolt up or down in the slot, or angularly by pivoting the member about the bolt. It is noted that the bolt I6 is horizontal and extends in a direction longitudinally of the lay beam I.

The lug I0 is fixed to the upper face of the leg I4 by a bolt I8. This bolt passes through a slot I9 in the lug I0 and a slot 20 in the leg I4. The slot I9 extends longitudinally of the lug, which is forwardly and rearwardly of the loom, and the slot 20 extends longitudinally of the lay, or at` right angles to the slot I9. When the bolt I8 is tightened they shuttle guiding plate 1 and lug Il) are supported by the member I2 and may be adjusted therewith. Thus, angular adjustment of the member I2 about the bolt I6 will adjust the vertical inclination of the plate 1 and vertical ad-v justment of the member will move the plate vertically.

The bolt I8 and slots I9 and 20 permit adjustment of the plate 1 relative tov the member I2. More specifically, when the bolt I8 is loosened the plate 1 and lug I0 may be moved horizontally forwardly or rearwardly or may be pivoted about the bolt to align the shuttle guiding surface 8 relative to the lay beam and reed. I havenot shown'any means for supporting the outer or left hand endof the back box plate because such means, if employed, may be of any suitable usual construction 1 which will permit the plate 1 to be adjusted by the improved supporting means: above described.

The extending of the lug l through the opening Il to the back of the sword permits the location of the supporting and adjusting means at a place where there is ample space and no interference with other loom parts. The supporting and adjusting devices may therefore be of the size required to provide ample strength and rigidity., Such devices are also convenientlyaccessible for adjustment purposes.

Having fully disclosed the preferred embodiment of my invention, I claim:

1. In a loom, the combination of a lay sword, a lay beam xed to the front face of said sword below the top thereof, a shuttle box including a back shuttle guiding plate positioned in front of said sword abovesaid lay beam, said plate having a lug extending rearwardly through an opening in said sword, and supporting means located at the back of the sword for supporting said lug and thereby said plate, saidmeans being adjustable to adjust the vertical inclination of said plate. 'f

2. In a loom, the combination of a lay sword, a lay beam fixed tothe 'front face of said sword below the top thereof, a shuttle box including a back shuttle guiding plate positioned in front of said sword above said lay beam,y said plate having a lug extending rearwardly through an opening in said sword, a supporting member located at the back of the sword and adjustably secured thereto for adjustment both vertically and angularly about a horizontal axis, and means adjustably securing said lugto said supporting member for adjustment of said lug land plate forwardly and rearwardly. l

3. In a loom,` the combination of a lay sword, alay beam fixed to the front face of said sword below the top thereof, a shuttle box including a back shuttle guiding plate positioned in front of said sword above said lay beam, said plate having an integral lug extending rearwardly through an opening in said sword, a vertically and angularly adjustable supporting member secured to the back of said sword adjacent said opening, and means for fixing said lug to said supporting member whereby said plate is supported by and adjustable with said member.

4. In a loom, the combination of a lay sword, a lay beam fixed to the front face of said sword below the top thereof, a shuttle box including a back shuttle guiding plate positioned in front of said sword above said lay beam, said plate having an integral lug extending rearwardly through an opening in said sword, a supporting member located at the back of the sword adjacent said opening, said member having a horizontal surface on which said lug rests, means securing said member to said sword for adjustment about a horizontal axis extending longitudinally of said lay beam, and means securing said lug on said surface for adjustment of said lug and plate with said member and forwardly and rearwardly relative thereto.

` 5. In a loom, the combination of a lay sword, a lay beam fixed to the front face of said sword below the top thereof, a shuttle box including a back shuttle guiding plate positioned in front of said sword above said lay beam, said plate having an integral lug extending rearwardly through an opening in said sword, a supporting member positioned at the back of said sword, said member having a vertical leg and a horizontal leg adjacent said opening, means securing said vertical leg to said sword for adjustment'of said member both vertically and angularly about a horizontal axis extending longitudinally of the lay beam, and means securing said lug to said horizontal leg for adjustment of said lug and plate both with said member and forwardly and rearwardly relative thereto.
